Just got a fairly cheap version from Ottinger. Not too loud because they're mostly rubber with metal spikes. It doesn't make for silent running but compared to metal tracks, they're not too bad. These are one size fits all but I find they'd be better for bigger shoes. Mine are a size 6 and could do with being stretched more taut. The only problem I've had is losing spikes. This version came with two spares which are easily inserted by pressing them (well it is a bit of work) through holes in the rubber. If you're unlucky they can catch on something under the snow and get jerked out. I think that is what happened to mine but I wasn't aware of losing them during the run.
On the whole I'm happy with them, you can run entirely normally on ice, they're light and uncomplicated to slide over the base of your shoes. The only thing is they're not for running on other surfaces, so if your route is partly tarmac and partly ice or snow they wouldn't be much good. We had ice and snow covering everything where I ran this morning, so that was straight-forward. Stuffed them in my pocket on the walk down and put them on when I got to the forest where I planned to run.
